Lin Yuan's concerns were not without reason, mainly because the blueprints drawn by Lin Ershuan were too detailed. Anyone in the industry could understand them at a glance; they had to beware of others taking advantage of their hard work.
Lin Jiaxin completely agreed with his daughter's words and repeatedly exhorted Lin Ershuan to differentiate the blueprints shown to customers from those used for his own work. The detailed blueprints should not be taken out. For customers, showing just the four main views — front, back, left, and right — should be enough.
Lin Ershuan nodded repeatedly, clutching the blueprints in his hand even tighter, as if afraid someone would snatch them away right that moment.
However, there was another issue that Lin Ershuan was quite unsure about. After much deliberation, he still asked, "This, this wheelchair, how should we price it properly? I've never seen this item before, and I have no idea what price to ask for it."
